Stoping Mining Methods Metallurgist & Mineral Processing

Cut-and-fill stoping is applicable to the mining of firm ore enclosed within walls, one or both of which are weak and heavy. The deposits may be tabular in form, dipping at angles steeper than the angle of repose of the broken ore (or flatter, if scrapers are employed for moving the ore in the ore passes), or to wide, thick ore bodies or masses.

SECTION 10 SHRINKAGE METHODS Mike Turner Australian

Shrinkage mining was a common stoping method prior to mechanised mining and the introduction of hydraulic fill. Sub-level stoping, cut and fill mining and sub-level caving have generally replaced shrinkage mining in Australia, Europe and Canada. The method is still used in a handful of non-mechanised mines in South America, Africa, Asia and Canada.
